The Gift For Betrayal.

The gods watched the fight with rapt attention so they couldn't help but notice that no warrior has been eliminated since the battle started. It is not that the Shadow of Despair can't kill them but he can't kill them while surrounded with enemies and outnumbered. He surely can't kill them with one attack. 

It is the resilience of the Warriors that made them form craters on the plane. No other class can smash into the ground like that without suffering but instead made the ground suffer in their place.

This unnatural resilience is why the Shadow of Despair is avoiding warriors. Other classes are the focus of his attention. They are teleported away with a single hit from the Shadow of Despair. 

So the Supreme beasts are reducing in number as the fight went on but they are not comforted by that because it is the warriors who are also the main class of Supreme beasts that can maintain their strength in the divine plane.
